This invention relates to sheet metal window frames provided with sliding sashes. i

The object of the invention is to provide a frame of simple construction by which the sashes can be readily removed from their frame without altering or inany way disturbing the jambs ofthe window frame;

Other objects of theinvention will become apparent as proceeds.

In the drawings: I it Figure 1 is an elevation of one stile of a window frame, with the head and-sill of the frame shown in section. and a fa'lse'head removed both sashes being shownin raised position; a Figure 2-is a fragmentary elevation ofthe said stile, with the sill shown in crosssection, and both sashes lowered;

and at the other end, by the sill 4.

Each stilehas a wide slot 5 extending in which the tongues 7 and 8 of the shashe s 9 and I 1.0 respectively,*are adapted V to slide.

At opposite/sides of the slot 5, the stile has inturned flanges 11 and 12', -adap ted. to w form smooth guiding surfaces for weather,

strips 13 and 141 secured to the tongues 7 and 8; respectively. v

The tongues each other bya parting head extending from" the top of thesill 4; to the bottom of the head 3, The parting bea ompr s manned sections and 16, the lower section being slightly longer thanieither of the: sashes '9. and 10. ,lvlhe purpose of this construction is,

7 and aimseparated from illustrated in Figure 4 ofthe drawing. It i will be obvious from inspection of this figure-- that. when the lower section 16 is removed from th'e stile 1, either ofthe sashes 9 and 10, maybe moved into therecess, formed by formed by theinturne-d flangesll" v and 12 of.

the stilfi 2 and the parting bead seatedfin l the channel members 6.

- TheiheadB of tl ewinclow framelis the finish head of the frame; it isinerely a box which permits both sashes 9 and 10 to slide clearaho've the joint 17 between the sections 15 and 16in order to permit the 'removal of the lower section The'finish head 18 (shown clearly in Figures 3 and 5) has flanges 19 and 20 formed on its opposite edges and section 16 is removed, in order to free the tongues 7 and S from the stile 2. The main 7 thing "in this construction is to form the several parts so that the sashes'can be removed from the frame without disturbing either or" the stiles 1 and 2. lVhen the sashes are removed, either or both of the-stiles can be readily disconnected and 'removed'from the jambs 26 and 27, respectively; The head 3, sill 4 and jambs 26 and 27 are suitably welded or otherwise permanently securedto each other; while the soifit 18 and stiles 1 and 2 are detachably connected to the head 3 and the said jambs, respectively. 7

The upper ends of the channel members 6 and 6 are provided with the usual pulley sheaves 28 and 29 for the chains/or cables 30 In prior constructions of sheet metal windows, the repair of broken counterbalancechains orthe parts of theframe'a'nd sash have necessitated the bodily removal of the whole stiles andsashes. In the present form," the sashes can be removed" first from the frames, and the stiles can then be removed hanging of the'sashes in the samemanner as. the common wooden sashes arelordlnarily hung n the usual wooden framesl 1 In the modification shown m Figures)? toll, inclusive, the sofiit l8 need'not be removed in order to efiect removal of, the sashes from the frame. In this form, one of the parting beads 'is' made in three sections provided with a; lip 41 adapted to seat in the upper end of the section 37 ,scr'ew bolts42 and 7 43 being used to secure the three sections' to each other. 1

Of course, the section 36 may be of any desired length, providing the combined length of sections 36 and 37 is greater than the length of the lower sash. It is more convenient to move the sashes to the lower end of the frame to ellect their removal; but it is obvious that the construction can be changed so that the sashescan be-removed from any part of the frame. All that is necessary is to provide forthe removal of some or all of a parting bead longer than the length of either or both sashes.

Tnthe form of the invention illustrated by Figures12to 16, inclusive, an inner and outer stile 2 is shown on both sides of a window. Both the inner and outer stile 2 is-divided into two sections, only the lower inner sections 2 being removable. The stile 2 is made integral and bent so as to-form a channel for the sash 9. The outer stile sections 2 are secured to the frame by a screw lv The inner side, which is in the form of an inturned. flange 11, is held in place byjascrew 45, which also holds the parting-bead 16; the intur-ned flange seating beneath the patring bead 16, with an aperture 46 therein alinin'g exactly with the screw 45 in'the parting bead'16..

Onthe opposite side of the window, ex-' actly the same construction is used so that upon the removal of the corresponding elements on the opposite sides, thev lower sash 9- may be removed,' and upon the'upper: sash 10 being lowered to a position corresponding to the lower sash 9 and upon the-removal of the parting bead,it'-likewisecan be'removed.

The removal'operation consists in, first,

the removal of screw lh' which will release one end of the stile member 2, and thenunscrewing the screw45'until it isiraised sufficiently to permit the withdrawal of the inturned flange 11; It is to be'noted'that the a screw 45 will still retain the parting bead in place, which is not'entirely withdrawnfrom the'channel member6. Upon-this operation being completed the lower sash 9 may be lifted'from the window frame. 1

If it is desired to alsoremove the upper sash 10, the same may belowered to the position usually occupied bythelower sash'9, and upon the screw 45 being unscrewed, the

parting bead 16 maybe lifted from the channel 6, which permits the ready removal of the upper sash 10. 1

. It will beunderstood, o f-course, that only the lower portion of the parting bead is to be removed, and further that exactlyfthesame operation may be performed on the opposite side ofthe window with the same result, since theconstruction isidentical on both sides. \Vh'at I claim is 1.
